10. PREVENTING HOSPITAL FIRES- A PANDEMIC INITIATIVE the department initiated a rigorous drive to assure safety and reliability of electricity supply to all the covid hospitals working 24 X 7 through its all district wise divisional electrical inspectorate . Electrical Inspectors visited the hospital installations physically of more than 4000 hospitals all across the Maharashtra every single installation of hospitals were thoroughly checked with all necessary measurements were taken by the sophisticated instruments . pitfalls were identified and conveyed to management . rectification were carried out within stipulated time Electrical Risk Assessment of Covid Hospitals during Pandemic All Dist. (Total Hospitals ) High Risk Installations Moderate Risk Installations Minimal Risk Installations Pvt. owned Hospitals/ Covid Care centres Govt.
